x%5E2-4x%2B12=0
Use the quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
where a=1, b=-4, and c=12
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-4%29+%2B-+sqrt%28+4%5E2-4%2A1%2A12+%29%29%2F%282%2A1%29+
x+=+%284+%2B-+sqrt%28+16-48+%29%29%2F%282%29+
x+=+%284+%2B-+4sqrt%28+-2+%29%29%2F%282%29+
x+=+2+%2B-+2sqrt%28+2+%29i+
